High-voltage connectors are extremely important components in the new energy automotive industry.

In the field of new energy automobile industry, high-voltage connectors are extremely important components, and are used in vehicle and charging facilities. The data shows that the current market size of connectors for new energy vehicles is 2.5 billion yuan. With the adjustment and development of new energy vehicles, the market size is expected to reach 8 billion yuan by 2020 in China.


Application scenario

In the field of new energy automotive industry, high-voltage connectors are extremely important components, and are used in vehicle and charging facilities. The main application scenarios of the high-voltage connector on the whole vehicle are: DC, plumbing PTC charger, wind heating PTC, DC charging port, power motor, high voltage wiring harness, maintenance switch, inverter, power battery, high voltage box, electric air conditioner, AC charging Mouth.

The requirements that the electric vehicle interface needs to meet are more stringent requirements for connector performance due to the diversity. The high number of insertions, current carrying capacity, heat resistance and vibration resistance are the factors to be considered in the development of enterprise products. As the power demand of the electric drive unit of the new energy vehicle is getting larger and larger, the working current and voltage of the connector are put forward higher and higher requirements. The traditional connection voltage is about 14V, and the voltage of the high voltage connector of the electric vehicle reaches 400- 600V.

In actual use, the connector is often encountered in overheating or burning, signal interference, etc., to meet the sealing and stability of the connector in harsh environments. Connector companies will do some testing to ensure the security of the connector during use.

The test items mainly include:

1, visual inspection, dimensional inspection, contact retention force, interchangeability, crimping pull-out force, cable fixing; 2 insertion and extraction force, normal operation, bending; 3, contact resistance, insulation Resistance, withstand voltage, temperature rise, over current; 4, electrical load; 5, vibration and impact; 6, salt spray; 7, simulated environment; 8, shell weather resistance; 9, chemical resistance; 10, shielding.

 

New energy vehicle high-voltage connectors need to adopt new materials with high temperature resistance in terms of material selection, and the requirements for sealing, shielding and waterproofing are higher than those of traditional automotive connectors, so the cost is relatively higher than that of general industrial connectors.
